具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
针对现有技术中的列车重联时没有对应的错误处理机制，当发现部分节点因不可控因素导致其无法参与重联时，将致列车信息有缺口，无法保证重联后列车信息的准确性的问题，本公开实施例增加了错误处理机制，当发现部分节点因不可控因素导致其无法参与重联而造成列车信息有缺口时，建立确认和修正机制，保证重联后列车信息的准确性和安全性。
下面参考附图描述本公开实施例的列车重联方法、系统和装置。在具体描述本公开实施例之前，为了便于理解，首先对常用技术词进行介绍：
列车重联，即对列车网络进行配置的全部过程，一般发生在列车上电或者列车长度(例如，增加节点或者减少节点)发生变化的时候。
协商确定过程，是指当列车发生重联时，列车上的每个服务端生成列车目录后，由列车上的第一服务端根据第一服务端所生成的列车目录，将列车构成信息确认报文发送至第二服务端，第二服务端根据列车构成信息确认报文，确认第二服务端所生成的列车目录与第一服务端所生成的列车目录是否一致，得到确认结果，而后将确认结果通知给第一服务端。
图1为本公开实施例所提供的一种列车重联方法的流程示意图。
如图1所示，该列车重联方法包括以下步骤：
S101，列车包括至少两个服务端，当发生列车重联时，至少两个服务端中的第一服务端生成列车目录。
列车包括至少两个服务端，本实施例中至少包括了第一服务端和第二服务端。通常，列车包括至少两个列车组，且对于每节列车组的车厢节点数并无限制，例如，列车可以为双节列车组、四节列车组、八节列车组、十六节列车组等。服务端指的是每节列车组的骨干节点，其连入到列车级网络中，每节列车组可以具有多个服务端，但在每次工作时，每节列车组只能具有一个服务端处于激活状态。
作为一种示例，参见图2，图2为本公开实施例中四节列车组列车示意图，列车组A和D均为4节车厢，列车组B和C为3节车厢。
需要说明的是，本公开实施例的列车重联方法在列车重联时，具有确认和修正功能，列车的确认和修正方法由服务端执行。在本公开的实施例中，服务端可以例如为网关，或者，服务端可以例如为信号系统，对此不作限制。
可选地，可以默认每节列车组的头车厢开启服务端的功能，其他车厢处于关闭状态，也就是说服务端设置于每节列车组的头车厢。
需要说明的是，在列车重联时，列车上所有列车组中的骨干节点均参与确认和修正的过程，包括冗余线路上的骨干节点，且每节列车组的每节车厢的网关均参与列车重联的过 程，包括冗余设备的网关。
在本公开的实施例中，第一服务端可以为当前发送确认状态请求信息的客户端所处的列车组的服务端。举例说明，参见图2，若当前发送确认状态请求信息的客户端所处的列车组为列车组C，列车组C的头车厢开启服务端的功能，且配置服务端为网关，则第一服务端为列车组C的头车厢的网关。
在本公开的实施例中，列车目录提供一有序的列车上所有被发现的列车组列表，其在列车重联后生成，当列车骨干网络拓扑计数发生改变时，列车目录都会被重计算。
在列车重联时，若某节列车组或者某节列车组上的一节或者多节车厢节点无法正常工作导致其无法计入至列车目录中，则此时的列车目录是不完整的，可能导致列车无法正常工作，例如，无法工作的原因为车厢断电，或者无法工作的原因为其他，本公开的实施例对此不作限制。
可选地，在列车重联时，列车的第一服务端生成列车目录，以触发后续判断过程。
S102，第一服务端向至少两个服务端中的第二服务端发起协商确认过程。
在本公开的实施例中，第一服务端和第二服务端所设置的列车组不同。
可选地，列车包括的至少两个服务端分别为对应列车组的头车厢的网关。
本公开实施例的列车重联的确认方法的发起者可以为列车上的客户端设备，或者，发起者可以为外接设备，或者，发起者可以为远程服务端，对此不作限制。本实施例以发起者为列车上的客户端设备示例。
可选地，客户端可以发送列车构成请求信息至第一服务端，第一服务端接收客户端发送的列车构成请求信息后，根据第一服务端所生成的列车目录，将列车构成信息确认报文发送至列车骨干网络中去，第二服务端可以从列车骨干网络中接收列车构成信息确认报文，以判断第二服务端与第一服务端协商确认所生成的列车目录是否一致。
其中，列车构成信息确认报文用于指示列车组的车厢节点信息。
S103，通过协商过程，第一服务端确认第一服务端所生成的列车目录与第二服务端所生成的列车目录是否一致，以在第一服务端所生成的列车目录与第二服务端所生成的列车目录不一致时，对第一服务端所生成的列车目录进行修正。
可选地，第一服务端可以根据第一服务端所生成的列车目录，与至少两个服务端中的第二服务端本地存储的列车目录进行比对，判断是否有缺失或者错误，若两者相同，则给出一致应答，此时无需对列车目录进行修正；若两者不同，则给出不一致应答，此时需对列车目录进行修正。也就是说，第一服务端可以根据第一服务端所生成的列车目录，与至少两个服务端中的第二服务端本地存储的列车目录进行比对，判断是否有缺失或者错误，若两者相同，则给出一致应答，此时无需对第一服务端所生成的列车目录进行修正；若两 者不同，则给出不一致应答，此时需对第一服务端所生成的列车目录进行修正。
进一步地，第一服务端根据第二服务端的通知，确认第一服务端所生成的列车目录与第二服务端所生成的列车目录是否一致；若第一服务端根据第二服务端的通知，确认第一服务端所生成的列车目录与第二服务端所生成的列车目录不一致，则第一服务端修正第一服务端所生成的列车目录。
具体地，在第一服务端与至少两个服务端中的第二服务端协商确认所生成的列车目录不一致时，需对第一服务端所生成的列车目录进行修正。为了通知第一服务端列车目录不一致的情况，可选地，第二服务端发送修正请求报文，从而第一服务端接收第二服务端发送的修正请求报文，其中，修正请求报文用于指示列车组的车厢节点修正信息；第一服务端根据车厢节点修正信息，对生成的列车目录中对应列车组的车厢节点信息进行修正；第一服务端通知第二服务端修正后的列车目录，以使第二服务端根据第一服务端的通知，确认修正是否成功。
本公开实施例对列车重联进行了优化，增加了防错纠错机制，能够有效保证列车信息的准确性及安全性。
本实施例的列车重联方法，通过当发生列车重联时，至少两个服务端中的第一服务端生成列车目录，第一服务端向至少两个服务端中的第二服务端发起协商确认过程，通过协商过程，第一服务端确认第一服务端所生成的列车目录与第二服务端所生成的列车目录是否一致，以在第一服务端所生成的列车目录和第二服务端所生成的列车目录不一致时，对第一服务端所生成的列车目录进行修正，保证了在列车重联时，生成的列车目录的准确性。
为了进一步提高列车信息的准确性及安全性，参见图3，在如图1所示实施例的基础上，在步骤S102前还包括：
S301，第一服务端接收客户端发送的确认状态请求信息。
在本公开的实施例中，确认状态请求信息的发起者可以为列车上的客户端设备，或者，确认状态请求信息的发起者可以为外接设备，或者，确认状态请求信息的发起者可以为远程服务端，对此不作限制。
可选地，客户端可以根据自身实际需求发送确认状态请求信息至该列车组的一个服务端，本实施例中记为第一服务端。
S302，第一服务端向客户端发送确认状态响应信息，其中，确认状态响应信息包括用于指示第一服务端是否已协商确认所生成的列车目录、第一服务端的列车目录的有效状态和/或列车拓扑计数器的有效状态。
可选地，确认状态响应信息主要包含如表1所示的信息。
表1
Figure PCTCN2018088193-appb-000001
当第一服务端收到客户端发送的确认状态请求信息时，给出确认状态响应信息，并发送确认状态响应信息至客户端。
本实施例的列车重联方法，通过第一服务端接收客户端发送的确认状态请求信息，第一服务端向客户端发送确认状态响应信息，能够有效提升列车信息的准确性及安全性。
为了清楚说明上一实施例，本实施例提供了另一种列车重联方法，图4为本公开实施例所提供的另一种列车重联方法的流程示意图。
参见图4，在如图1所示实施例的基础上，步骤S102具体包括以下子步骤：
S401，第一服务端接收客户端发送的列车构成请求信息。
可选地，客户端发送列车构成请求信息至其所处的列车组的服务端，即第一服务端，第一服务端接收客户端发送的列车构成请求信息，以触发后续步骤。
S402，第一服务端根据第一服务端所生成的列车目录，向第二服务端发送列车构成信息确认报文，其中，列车构成信息确认报文用于指示列车组的车厢节点信息。
在本公开的实施例中，列车构成信息确认报文包括：列车构成信息确认报文功能标识、列车组标识和/或车厢节点信息。
其中，列车构成信息确认报文功能标识，用于指示列车构成信息确认报文用于协商确认列车目录；列车构成信息确认报文的列车组标识，用于指示发送列车构成信息确认报文 的第一服务端所在列车组；车厢节点信息，包括车厢节点数目和/或车厢节点列表；车厢节点列表包括各车厢节点的节点号和节点方向。
可选地，第一服务端在接收到客户端发送的列车构成请求信息后，将列车构成信息确认报文发送至列车骨干网络中去，而后，第二服务端可以从列车骨干网络中接收列车构成信息确认报文，以判断自己与第一服务端协商确认所生成的列车目录是否一致。
可选地，列车构成信息确认报文主要包含如表2所示的信息。
表2
Figure PCTCN2018088193-appb-000002
可选地，在第一服务端与至少两个服务端中的第二服务端协商确认所生成的列车目录一致时，不作任何处理；在所生成的列车目录不一致时，对列车目录进行修正。
具体地，至少两个服务端中的第二服务端接收第一服务端发送的列车构成信息确认报文，可以与本地存储的列车目录中的该报文信息中的cstUUID所存信息进行比对，判断是否有缺失或者错误，给出相应的应答报文，若两者相同，则给出一致应答，此时，将当前的确认状态修改为确认，向客户端应答确认无误，无需对列车目录进行修正；若两者不同，则给出不一致应答，此时，可以向客户端应答确认有误需要修正，等待修正。
本实施例的列车重联方法，通过第一服务端接收客户端发送的列车构成请求信息，第一服务端根据第一服务端所生成的列车目录，向第二服务端发送列车构成信息确认报文， 其中，列车构成信息确认报文用于指示列车组的车厢节点信息，进一步提升列车信息的准确性及安全性。
为了清楚说明上一实施例，本实施例提供了另一种列车重联方法，图5为本公开实施例所提供的另一种列车重联方法的流程示意图。
参见图5，在如图1所示实施例的基础上，步骤S103包括以下子步骤：
S501，第一服务端根据第二服务端的通知，确认第一服务端所生成的列车目录与第二服务端所生成的列车目录是否一致。
具体地，第一服务端与至少两个服务端中的第二服务端协商确认所生成的列车目录是否一致，例如，第一服务端可以根据所生成的列车目录，与至少两个服务端中的第二服务端本地存储的列车目录进行比对，判断是否有缺失或者错误，而后，第二服务端可以将通知发送至第一服务端，以通知第一服务端列车目录不一致的情况。
S502，若确认第一服务端所生成的列车目录与第二服务端所生成的列车目录不一致，第一服务端接收第二服务端发送的修正请求报文，其中，修正请求报文用于指示列车组的车厢节点修正信息。
在本公开的实施例中，修正请求报文包括：修正请求报文功能标识、列车组标识和/或车厢节点修正信息；

可选地，第一服务端所生成的列车目录与至少两个服务端中的第二服务端本地存储的列车目录进行比对，若两者相同，则给出一致应答，此时无需对列车目录进行修正；若两者不同，则给出不一致应答，此时需对列车目录进行修正。具体地，在第二服务端给出不一致应答之后，还会向第一服务端发送修正请求报文。进而第一服务端接收第二服务端发送的修正请求报文，以根据修正请求报文对生成的列车目录中对应列车组的车厢节点信息进行修正。
作为一种示例，假设某节列车组Z(列车组Z的骨干节点为第二服务端)确认有误需要修正，并且修正规则为在车厢节点X和车厢节点Y中插入车厢节点A、B和C三个节点，修正过程如下所示：
